Answer 2

Always follow DMAS rule.

3/5 × 5/24

5 canceled its 3/24 means 1/8

3/16 × 4/3

3 canceled its 4/16 means 1/4

-7/18 * 15/-7

-7 canceled and its 15/18

now do addition first

1/4 + 15/18

LCM is 36

9+15*2/36

9+30 = 39/36 = 13/12

Now subtraction,

13/12 - 1/8

LCM is 36

13*3 - 1×4.5

39×4.5

=179.5
